Abstract (en)
A radiographic imaging system is adapted to reconstruct a tomographic image in a given cross section of a subject from projection images of a subject acquired in tomosynthesis imaging. The radiographic imaging system comprises a frequency filtering processor for producing band limiting image signals having different frequency response characteristics from projection image signals corresponding to the projection images; a non-linear conversion processor for performing non-linear conversion of band limiting image signals to reduce a portion of band limiting image signals exceeding a given value; an integration processor for adding up band limiting image signals having undergone non-linear conversion through the non-linear conversion processor to produce converted image signals; and a back projection processor for reconstructing the tomographic image in the given cross section of the subject from the converted image signals corresponding to the projection images.
